Aiming[]
The aiming of Dualbarrel is very strange. Like its name suggests, Dualbarrel have 2 barrels that starts out in the position of a diep.io Flank Guard and have the appearance of arras.io single. However, One follows the x position of mouse and the other follows y position so it would be extremely hard to aim at something. When firing, One would follow Left Click and e and the other would follow the right key.
